 # Greptime Command Line Interface
 
-The `greptime` command provided by the pre-built binary can start/stop GreptimeDB and pass configuration options. To execute the binary with `greptime` instead of the ad-hoc `./greptime`, you might need to move the binary into the system `bin` directory or add the binary path to the `PATH` environment variable.
+The `greptime` command can start/stop GreptimeDB and pass configuration options. 
+
+## Install the Greptime CLI
+
+The Greptime CLI comes bundled with the GreptimeDB binary.
+After [installing GreptimeDB](/getting-started/installation/overview.md),
+you can execute the `./greptime` command within the GreptimeDB directory.
+
+For convenience, if you wish to run commands using `greptime` instead of `./greptime`,
+consider moving the CLI binary to your system's `bin` directory or appending the binary's path to your `PATH` environment variable.
+
+## CLI Options
 
 The `help` command lists all available commands and options of `greptime`.
